I use Django Ninja, Zod, InertiaJS+Vue and its as easy as using Django's templating engine, but static typing ensures my view doesnt emit unrepresentable data, my TS doesnt accept unrepresentable data, Vue+TS dont allow logic errors in template. AI makes it effortless. Again, the loaded page is a function of the data supplied at the view.
With HTMX, I'm writing several server-side functions to mutate the DOM imperatively and using HTML attributes to call them. Its great for forms but that shopping cart example needs code scattered across multiple functions and templates.
